What is a proper repair procedure for damaged flared or flareless steel tube fittings?

Replacing all parts with new parts from the same manufacturer is a proper repair procedure for damaged flared or flareless steel tube fittings because it ensures the integrity and compatibility of the components in a fluid power system. Using new components from the same manufacturer means that the specifications and materials will match, maintaining system pressure ratings and performance standards. This method minimizes the risks of leaks or failures that could arise from mismatched or damaged components.

In fluid power applications, maintaining a secure and leak-free connection is critical for operational safety and efficiency. New parts can guarantee that the fitting surfaces are undamaged and will provide reliable sealing capabilities. This approach is particularly important in systems conveying hydraulic fluids under high pressures.

Visual inspection and the idea of repairing parts may not guarantee the same level of reliability, as even small imperfections can lead to failures in high-pressure systems. Utilizing an O-ring and Teflon tape might improve sealing in certain contexts but does not address underlying wear or damage in the fittings themselves. Therefore, opting for a complete replacement is the safest method to ensure system functionality and safety.
